hello, can anyone tell me where the heck is the fuel pump relay on the W124 E420? I need to replace it but can't find it. I had a 300E, but on thi car I have no clue. HELP!!!!!!!!!!!!!!!!!!!!!!!

You can't find it because it is built into the MAS Relay.

Steve

ok if the fuel pump relay is in the MAS, then were is the MAS in this model car? I had a w124 E300, and in that car it's behind the battery, but with the E420 I havn't the slightest clue. Please help!!!!!!!!!!

According to my CD, in the E420 it's inside the car under the right side of the rear seat in a depression in the floor.

Cheers
JJ

mmmmm. And if the windows or roof got left open during past rain storms chances are the depression got flooded.

All the previous posts are NOT correct!!!!!

MAS relays were only on CIS-E injected cars!

The fuel pump relay on the 1993-95 E320's (300E in 93) is located behind the battery near the ABS computer. GREEN relay with fuse.

The W124.034 chassis (400E/E420) is under the seat on the passenger side.
